Title: Conveyor systems and conveyor belts
Inventor: EWEN JOHN R
IPC: B65G17/02
Filed: 1993-03-03
Abstract: ABSTRACT OF THE DISCLOSURE            A conveyor system comprises a conveyor belt supported and driven by engagement between an under surface of the belt with   a   pair   of   parallel   spaced   cables   extending longitudinally along the belt.  The cables are driven to drive  the  conveyor  belt  and  a  feed  chute  is  mounted adjacent a loading end of the belt.  Material is fed on to the belt through the feed chute and a pair of spaced side plates  are provided to define a channel therebetween for containing material  loaded on to  the  belt.   Each  side plate has a lower edge adjacent to but spaced from the conveyor  belt  surface  and  the  belt  is  provided  with scrapers which pass through these gaps to scrape material from the lower edges of the side plates.   This prevents the build-up of material between the lower edges of the side plates of the conveyor belt and so reduces belt wear and frictional loads.

Patent CA-2096161-A1 (CA)
Inventor: LAMBERTI DONNA M
IPC: G06F17/27
Filed: 1993-05-13
Abstract: A  user/computer  interface  is described  that  employ  a constrained  natural language-form  input.   The  computer employs a feedback method to reinforce a user's confidence and knowledge  that  the  computer  comprehends  a  query  or instruction.  The user interface initially parses a user's natural language-form input into a case frame.   The case frame is then filtered into a goal-expression that comprises a verb  and  remaining  syntactical  portions  of  the  input query/instruction.    The   system   then   paraphrases   the goal-expression into constrained natural language-form and communicates the paraphrase to the user for confirmation that the computer system has correctly interpreted the user input.  The computer also compares the goal-expression with prestored goal-expressions to determine a match and then performs an action in response to a match being found.

Title: Multiple file name referencing system
Inventor: MILLER THOMAS J
IPC: G06F17/30
Filed: 1993-07-06
Abstract: A multiple file name referencing system stores multiple file names in a file. These multiple file names include an operating system formatted file name and an application formatted file name. When an operating system formatted file name is created or renamed, the multiple file name referencing system automatically generates an application formatted file name having a potentially different format from, but preserving the extension of, the operating system formatted name. The multiple file name referencing system similarly generates an operating system formatted name upon creation or renaming of an application formatted name. A B-tree is provided which contains an operating system entry for the operating system formatted name and an application entry for the application formatted name, each entry containing the address of the same file to which both names refer. The multiple file name referencing system converts the operating system formatted file name to the application formatted file name by accessing the B-tree with reference to the operating system entry, and vice versa. As a result, either file name can be used to directly reference the file without requiring additional file name translation.

Title: Ground fracturing probe
Inventor: KOSAR KEITH M
IPC: B09C1/00
Filed: 1993-10-15
Abstract: ABSTRACT           A ground fracturing probe to form fractures in subsurface formations includes an elongate, hollow body with a conical penetrating tip at its distal end. A threaded tool joint is at the other end of the body to allow the probe to be coupled to the drill string of a drilling rig. A helical flight is on the exterior surface of the body and extends along a portion of the body length between the tool joint and the penetrating tip. The helical flight varies in diameter over its length to define a cutting zone adjacent the penetrating tip, an injection zone above the cutting zone and a sealing zone above the injection zone. The helical flight increases in diameter in the cutting zone from the tip to the injection zone but decreases abruptly in diameter at the injection zone. The diameter of the flight remains constant in the injection zone and increases in diameter at the interface between the injection zone and the sealing zone. The diameter of the flight remains constant over the length of the sealing zone but is greater in diameter in the sealing zone than in the cutting zone. Orifices are provided in the body within the injection zone and communicate with the interior of the body to allow fluid pumped into the body under pressure to be discharged. The increased diameter of the flight in the sealing zone inhibits discharged fluid from travelling to the ground surface along the probe.

Title: Orifice Fitting with Venting Passage and Injection Seal
Inventor: TOMKINS MURRAY R
IPC: G01F1/42
Filed: 1994-02-25
Abstract: An orifice fitting for measuring the flow of gas through a pipeline in which the orifice fitting has a body including a pair of opposing body plates that define a body chamber.          Passing through both body plates is an aligned flow passage for attachment to a gas pipeline.   One of the body plates includes an access opening that is selectively covered and sealed by a hatch.   A carrier having a carrier chamber is movably positioned within the body chamber so that the carrier chamber can be selectively aligned with the flow passage or the access opening.  Removably positioned within the carrier chamber  is  an  orifice  disk  having  an  orifice  of  a predetermined size through which gas can flow when the carrier chamber is aligned with the flow passage.  The carrier chamber is sealed from the body chamber by seal rings positioned on opposing sides of the carrier and biased against the body plates.  When the carrier chamber is aligned with the access opening,  an  annular  injection groove positioned  on each sealing ring communicates with respective injection passages extending through the  body plates,  thereby permitting  a sealant to be injected into the injection groove for emergency sealing of the carrier chamber.  The orifice fitting further includes a valve assembly extending through one of body plates and communicating with the carrier chamber.  Extending from the valve assembly is a venting passage that permits the gas from the carrier chamber to be vented to the atmosphere at a distance from the valve assembly.
